The primary objective of research and development in educational planning is to improve the quality of education by identifying and addressing the factors that affect student learning.

Experimental research is not commonly used in educational planning because it is difficult to control all of the variables that can affect student learning in a real-world setting.

All of the above challenges are faced in conducting research in educational planning. Lack of funding can make it difficult to carry out large-scale studies, lack of access to data can make it difficult to obtain the necessary information, and lack of trained researchers can make it difficult to design and implement effective research studies.

Research and development in educational planning plays a vital role in addressing the challenges faced by the education sector by identifying the root causes of educational problems, developing and evaluating innovative solutions to educational problems, and informing policy and decision-making in the education sector.

Research and development in educational planning can contribute to the achievement of the SDGs by identifying and addressing the educational needs of marginalized and disadvantaged groups, developing and evaluating innovative approaches to teaching and learning, and informing policy and decision-making on education at the national and international levels.
